Thermal conductivity of diamond-loaded glues for the ATLAS particle physics detector
The ATLAS experiment is one of two large general-purpose particle detectors
at the Large Hadron Collider (LHC) at the CERN laboratory in Geneva,
Switzerland. ATLAS has been collecting data from the collisions of protons
since December 2009, in order to investigate the conditions that existed during
the early Universe and the origins of mass, and other topics in fundamental
particle physics. The innermost layers of the ATLAS detector will be exposed to
the most radiation over the first few years of operation at the LHC. In
particular, the layer closest to the beam pipe, the B-layer, will degrade over
time due to the added radiation. To compensate for its degradation, it will be
replaced with an Insertable B-Layer (IBL) around 2016. The design of and R&D
for the IBL is ongoing, as the hope is to use the most current technologies in
the building of this new sub-detector layer. One topic of interest is the use
of more thermally conductive glues in the construction of the IBL, in order to
facilitate in the dissipation of heat from the detector. In this paper the
measurement and use of highly thermally conductive glues, in particular those
that are diamond-loaded, will be discussed. The modified transient plane source
technique for thermal conductivity is applied in characterizing the glues
across a wide temperature range

Delayed umbilical cord clamping: A state of the science
The purpose of this paper is to explore the state of the science related to delayed versus early umbilical cord clamping. This interprofessional change in practice and protocol needs to take place within obstetric practice, which can be made up of obstetricians, midwives, nurse practitioners, and nurses. Patients must be educated by their providers so that they can better understand the care being performed. A search of the literature published through PubMed was conducted using the key phrases delayed umbilical cord clamping (DUCC), benefits of delayed cord clamping, and umbilical cord protocols. The search yielded 133 titles, which was limited to peer-reviewed, full-text research articles between the years 2011 to January 2016. After reading through the articles, another 100 were excluded because they did not include extensive information regarding the benefits of DUCC and/or management strategies for future policy development with 33 remaining for inclusion in this review. In research, the benefits of DUCC are the results of the influx of stem cells and iron in addition to the supplemental blood provided to the newborn. The disadvantage is the increased risk for hyperbilirubinemia in newborns. It can be maintained that the benefits of DUCC outweigh the disadvantages for both mothers and newborns. It is necessary that the interprofessional team implements research found on delayed versus early cord clamping in the form of evidence-based practice to deliver more complete care to women and newborns
Resources for Workplace Diversity: An Annotated Practitioner Guide to Information
[Excerpt] We are pleased to offer this updated edition of Resources for Workplace Diversity: An Annotated Practitioner Guide to Information, a unique offering of The Workplace Diversity Network. Our goal is to assemble a selected, annotated list of compelling and useful resources available to help diversity practitioners create organizations that are diverse and productive. As a working group, we agreed that useful resources would include newly published books as well as historic, seminal works that provide insight and illumination irrelevant of their age. In the updated edition, we’ve expanded existing sections, added new ones and referenced online access where possible. Designed with practitioner needs in mind, Resources for Workplace Diversity is meant to be an evolving document, one that will grow according to the needs and recommendations of its users. To capture the advantage of networking, we invite you to suggest additional resources that you have found to be valuable
Lagrangian Structure Functions in Turbulence: A Quantitative Comparison between Experiment and Direct Numerical Simulation
A detailed comparison between data from experimental measurements and
numerical simulations of Lagrangian velocity structure functions in turbulence
is presented. By integrating information from experiments and numerics, a
quantitative understanding of the velocity scaling properties over a wide range
of time scales and Reynolds numbers is achieved. The local scaling properties
of the Lagrangian velocity increments for the experimental and numerical data
are in good quantitative agreement for all time lags. The degree of
intermittency changes when measured close to the Kolmogorov time scales or at
larger time lags. This study resolves apparent disagreements between experiment
and numerics.Comment: 13 RevTeX pages (2 columns) + 8 figures include
